alias creations from ldap

[Arnaud HERVE]

Hi, I'm configuring a bsd machine on an intranet, and I'm looking for a  
coonection between Bind and Openldap, according to which Bind would  
automatically create aliases like www.johndoe.yo pointing to employee John  
Does' website on the http server, just by the registration of John Doe in  
ldap.

If possible just point me to a tutorial, and I'll take my time to read it.
